Just picked up an F30 335i sport. Loving the car, going to be hard keeping it under 4500 rpm for long. Already got pulled over for speeding and female officer let me off cause i apologized and she liked the car (melbourne red).

Not loving the Pirelli Cinturato P7 18" run flats. This is my first Bimmer, and was thinking of putting on Pilot Sports same sizing as my OEM 18" on the same rims. Did this tire work well on the e90? Will it effect the TPMS?

Any ideas?

If you're gonna get new tires all around, get some 245s. 225s are too thin in my opinion.

Yeah, should have gave more info. I don't want to go staggered, and I want to stay 18". I consider this set up cheaper and easier to deal with when problems occur with tires or rims.

I also really like the the new 18 sport line rims. I'll post pictures soon, but they look great.
No interest in any run flats either.
Newbie question but could I get a bit wider tire on the Sport line 18 rim?

Yes. You can. But don't go too crazy.

How wide can we fit on there? I'd love a little more grip in the rear on a 335i.

Personally, I'll stick with run flat tires, as there doesn't seem to be a large detriment in performance or comfort any longer vs non-run flat tires, and I don't want to haul around a spare. I am probably going to go with a summer performance tire like the Pirelli P Zero (when they release the 225/45R18), but I'll still use the run flat version and keep my Pirelli P7 Cinturato All Season for the cold part of the year (we don't really have much of a winter here in Dallas).

245 pushing it? 235 maybe?

I'm not an expert on fitting tires and I'm new to RFTs, but rim widths do not dictate a single tire width size. The width of a rim can fit a range of tire widths. My personal feeling is that BMW went with a thinner tire to promote better MPG. If you do change the width of your tires, I think you shouldn't stagger them since the wheels aren't staggered. Keep them all the same width whatever you go with. Hope this helps.

why do you guys think that the Pirellis suck? I have them adn my ride is great. They seem to have great grip thus far and ride very smooth for run-flats

Pirellis are great tires. I've had experience with them on a Scion TC and Lamborghini Gallardo (odd combo, I know) and they don't seem to last very long at all. A friend swapped the TC pirellis for continentals and they ride a lot softer and quieter, and the Lambo got Michelins and they are some the best tires I've felt, even in such a rough riding car. And they both have lasted a long time! Even with the tire spinning tendencies of the latter
